DETAILS: Imaged on 11-06-05 with the 12.5" Truss RC on a Paramount ME Robotic German Equatorial Mount, using an ST-10XME at f6.8 and Tru-Balance filters. Three hours of unbinned Luminance combined with one hour each of RGB filtered frames, using CCDSoft, MaxIm DL, RegiStar, Photoshop CS, various plug-ins and other software processing techniques. Updated 11-19-05 by processing Luminance raw frames with newly acquired CCDStack Image Processing Software.
COMMENTARY: NGC772 is a disturbed spiral galaxy located in lthe Constellation Aries at an approximate distance of 100 million light-years, receding from our galaxy at 2400 kilometers per second. It is a large galaxy, about twice the size of the Milky Way, at around 200,000 light-years. NGC770 is the bright dwarf elliptical galaxy above and slightly left of NGC772. It lies about the same distance and is possibly, or at least partially responsible for the perturbed nature of NGC772.
